Long after the war's end, official World War II records listed the German submarine U-110 as sunk on 9 May 1941 by a British convoy—a deliberate deception that hid the actual capture of a submarine that contained a working Enigma machine, codebooks, charts, and ciphers. As the official British historian of the naval war, Stephen Roskill did not reveal the secret in his authorized account.

When this book was first published in 1959, the author set the record straight about the sinking but continued to hold back details of Ultra. Now, a new introduction puts the capture of U-110 into context and makes clear its vital importance to the code-breaking program of the Allies in World War II. Roskill's work is based on both documentary and eyewitness evidence and provides the most authoritative history of how the Enigma machine became a key instrument of the war effort.

Stephen W. Roskill, a retired captain in the Royal Navy and author of the official history of World War II at sea, has written a number of highly regarded books, including Churchill and the Admirals. He lives in England.

Praise for The Secret Capture

"Though short, The Secret Capture provides the reader with an Interesting glimpse into British naval policy during World War II, especially with regard to convoy tactics and anti-submarine warfare. The authors are both noted historians and very capable writers, and, at times, the book flows like a well-written novel…An excellently researched and well authored book that provides a unique look into a unique event in the Battle of the Atlantic."
